ADJUSTABLE BAR AND BRACE FOR HANDLING PLOWSHARE;

SPECIFICATION formingpart of Letters Patent No. 642,396, dated January30, 1906.

Application filed May 1, 1899. Serial No. '715;091. (No model.)

To ctZZ whom it may concern:

Be it known that I, MICHAEL WERNIMONT, a citizen of the United States,residing at Asbury, in the county of Dubuque and State of Iowa, haveinvented certain new and useful Improvements in Adjustable Bars andBraces for Handling Plowshares; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

In the sharpening and pointing of worn plowshares there has been greatdifficulty experienced from the fact that when the share is subjected tothe influences of heat and pounding it frequently warps or breaks, andwhen so warped it is next to impossible to again fit it into its formerposition so/ that it will scour and properly cut and turn over thefurrow.

The object of this invention is to overcome these difliculties and torigidly hold plowshares of diiferent patterns and sizes to their normalshape and prevent them from warping or bending when in the process ofsharpening or pointing.

Afurther object is to straighten and bring back to the normal shapeplowshares which have been warped in previous sharpening, all of whichwill be fully developed in the following specification when viewed inconnection with the accompanying drawings.

For the better'understanding of my invention attention is called to thefollowing specification and drawings accompanyingthe same, in which-Figure 1 is a perspective taken from the under side of a plowshare withmy device attached thereto. Fig. 2 is a perspective of one of theadjusting-braces. Fig. 3 is a perspective of one of the braces which isadapted to adjust with Fig. 2. a plate for adjustment with the landsideof the plowshare, and Fig. 5 is a side elevation of the device attachedto the plowshare.

Like letters of reference denote corresponding parts in all thedrawings.

In the drawings, A designates a plowshare having the point a andprovided with the holes 1) and N for attachment tothe plow.

B is a bar of iron having a beveled point, which is adapted to fit intothe cavity din Fig. 4 is a perspective of the point of the plowshare.This bar B is provided with numerous holes 0, f, g, and P. There is alsoa slot D in said bar. A plate E (shown in Fig. 4) is adjustably fittedto the outside of the plate B and securely held in position by the bolts1' and j for the purposes presently to appear.

The rear end of the plowshare A is connected to the rear of the bar B bytwo adj ustable plates G and H. The plate G is provided with a slot 7c,extending nearly its entire length, and also a bolt-hole e and thethumb-screws n. The thumb-screws are set in one side of the end of theplate for the purposes hereinafter to appear.

The plate H, as shown in Fig. 3, consists of a cen tral strap bent atright angles at one end and formed into a transverse plate at the otherend, having therein a slot 0, and is also provided with the bolt-holes pand q.

The manner of using my device is as follows: The point of the bar B isinserted in a cavity (1 beneath the plow-point parallel with thelandside of the point and is adjusted to meet the different shapes ofthe cavities din various plows by the bolt 0, inserted in some one ofthe numerous holes 0 and passing through the landside. By means of thisbolt 0 the bar B is rigidly fastened to the inner side of p theplow-point and prevents, with the other parts hereinafter described, anywarping of the plow-point when heated.

In order to hold the point of the plowshare from warping in anotherdirection, a plate E (shown in Fig. et) is loosely bolted to the bar Bbythe bolt 1; and the bolt j is inserted in one of the slots m andpasses through the slot D of the bar B. If the rear end of the plowpointis perpendicular, as shown in Fig. 5, then the plate E is set as shownin Fig. 5 and held by the bolt 1' and the bolt j, which brings thesquare end of the plate E rigidly against the perpendicular end F of theplowpoint. If, however, the end F forms an obtuse angle with the base ofthe plow-point, then the bolt j is raised or lowered in the slot m toadapt it to fit snugly against the rear end F of the plow-point. If theend F is an acute angle, then the plate E is turned upon the pivot ofthe bolt '0', and the other end I is placed against the end F and thebolt j is inserted in the other slot at near the end I.

In this manner the bar B and the plate E are adapted to be adjusted toplow-points having different rear ends and different cavities beneaththe point.

It will be observed that when the parts E and B are assembled in themanner specified the end of the plate E may be adjusted to heels ofplowshares of any angle and when adjusted will not interfere in eithermeasuring or observing from the rear of the bar B any curvature orwarping that maybe in the point of the plow.

For the purpose of holding the plowshare Afrom warping along the upperedge and center when it is being sharpened the plate Gis looselyfastened by the bolt e to the rear end of the plowshare, and the plate His loosely fastened by a bolt 4" passing through the hole q and the slot7c of the plate G. This plate His further secured to the bar B by thebolt H passing through one of the holes P. After the plates G and H havebeen loosely attached to the bar B and the share A the bolts h, r, K,and c are screwed up, and this forms a rigid brace from the bar B to theouter end of the share A. If the share be curved at the outer end, thenthe plate G is adapted to meet such curvature by the thu mbscrews 77.,which are situated to one side of the hole 6 of the plate G. It will beseen that by these thumb-screws n the plate G may be turned at an anglewith reference to theshare A and adapted to any curvature of the outerend of the share. Again, for the purpose of adj usting it to plowsharesof different lengthsfor instance, if the plowshare only extendedslightly beyond the hole l -then the bolt 6 would pass through the holeN of the plowshare A and the plate G would be turned upon the pivot ofthe bolt 7' and the bolt would be turned to the inner end of the slot 0of the plate H, and if it appeared to be too short for the brace to beadjusted to the share of that length then the bolt 7L would be insertedin the hole P nearest to the plow-point, or if the plowshare was longerthan the one shown in Fig. 1 then the bolt It would be inserted in thehole P at the outer end of the bar B.

Vhen the bolt 0 is inserted in one of the holes 0, whereby the outer endof the bar 13 is caused to turn outside of a perpendicular and notparallel with the part S of the brace II, then there is inserted aset-screw in the holef or g, which presses against the upper or lowerend of the part S and adjusts the part S to the bar 13, and thus therigidity of the brace between the share A and the bar B is maintained.

It will be seen by the use of these various plates adjusted in themanner above described that they will be adapted to exactly tit andrigidly hold all plowshares of different length, width, and spread, andwhenever the plowshare is subjected to heat or pounding it will retainthe same position that it had when removed from the plow; also, afterthe plowshare has been sharpened or pounded and tempered it can bereturned to the plow and exactly fitted in the position it was beforesharpening.

After the device has been adjusted to the plowshare then the device maybe used in the place of tongs or other tools for handling plowshareseither in the fire or upon the anvil.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is-

1. In a device of the character described, a bar provided with means foradjust-ably securing it at one end to the rear of a plowpoint and abrace for connecting the rear end of said bar with the outer end of aplowshare, consisting of two rods slotted at right angles to each other,for the purposes shown.

2. A device of the character described, consisting of a bar providedwith means for adj ustably attaching it to the under side of aplow-point, a plate adj ustably attached to said bar and adapted toengage the rear of the plow-point, and a brace for adjustably connectingthe rear of said bar, and the outer end of a plowshare, the plate andbrace being slotted at right angles to each other, for the purposesshown.

3. A device of the character described, consisting of a bar 13, adaptedto be adjustably secured by bolt (J, to the landside of a plowpoint, anda brace formed of the two parts G and H,ad j ustabl y secured togetherand adapted to be adjustably secured to the rear of the bar Band theouter end of a plowshare, as and for the purposes shown.

4. An implement of the class described, comprising the plate B adaptedto engage the under side of the plow-point, the plate E having one ofits ends square and the other formed at an acute angle and pivoted tothe plate B, and provided with slots whereby it may be adjusted toheelsof plowshares having different angles, and so adjusted to the plateB that it shall not interfere with measurements or line of observation,and an adjustable brace con necting the rear'of the plate 13 with therear of the plowshare, for the purposes shown.

In testimony whereof I aifix my signature in the presence of twowitnesses.
